Comparison of the therapeutic efficacy between the ketogenic diet and conventional diet control in reducing epilepsy (≥50% reduction in epilepsy). Experimental group refers to the group on a ketogenic diet, with a total sample size of 111 cases, while CAU represents the control group on a conventional diet, with a total sample size of 114 cases. Events indicate the number of cases with a ≥ 50% reduction in epilepsy. RR indicates the relative risk ratio, where RR > 1 indicates that the number of cases with a ≥ 50% reduction in epilepsy in the ketogenic diet group is multiplied by the ratio compared to the control group on a conventional diet. The 95% confidence interval (95%-CI) reflects the possible range of effect sizes to support the results. I2 is used to evaluate the magnitude of heterogeneity between studies, with I2 < 50% indicating an acceptable level of heterogeneity. (A) Comparison of the therapeutic efficacy of ketogenic and conventional diets in reducing epilepsy by at least 50% at 3 months, with a funnel plot to assess publication bias. (B) Sensitivity analysis of the therapeutic efficacy of ketogenic and conventional diets in controlling epilepsy at 3 months, evaluating the source of heterogeneity. (C) Subgroup analysis of different types of ketogenic diets to evaluate the heterogeneity of the studies.
